6 . Most environmental pollution on Earth comes from humans and their inventions, such as cars or plastic. Today, car emissions (排放物) are a major source of air pollution leading to climate change, and plastics fill our ocean, creating a significant health issue to marine (海洋的) animals.

And what about the electric light, thought to be one of the greatest human inventions of all time? Electric light can be a beautiful thing, guiding us home when the sun goes down, keeping us safe and making our homes bright. However, like carbon dioxide emissions and plastic, too much of a good thing has started to impact the environment. Light pollution, the inappropriate use of outdoor light, is affecting human health, wildlife behavior and our ability to observe stars.

Light pollution is a global issue. This became obvious when the World Atlas of Artificial Night Sky Brightness, a computer-generated map based on thousands of satellite photos, was published in 2016. Available online for viewing, the map shows how and where our globe is lit up at night. Vast areas of North America, Europe, the Middle East and Asia are glowing (发光) with light, while only the most remote regions on Earth (Greenland, Central African Republic and Niue) are in total darkness. Some of the most light-polluted countries in the world are Singapore, Qatar, and Kuwait.

Sky glow is the brightening of the night sky, mostly over cities, due to the electric lights of cars, streetlamps, offices, factories, outdoor advertising, and buildings, turning night into day for people who work and play long after sunset.

People living in cities with high levels of sky glow have a hard time seeing more than a handful of stars at night. Astronomers are particularly concerned with sky glow pollution as it reduces their ability to view stars.

More than 80 percent of the world’s population, and 99 percent of Americans and Europeans, live under sky glow.

1. What can we learn from paragraph 2?

A．The use of outdoor light must be forbidden.

B．Electric light is the greatest human invention.

C．Electric light is the main factor to keep us safe.

D．Electric light has both advantages and disadvantages.

2. Which of the following places is least affected by sky glow?

A．Qatar.

B．Niue.

C．Kuwait.

D．Singapore.

3. Why do astronomers especially complain about sky glow?

A．Sky glow costs too much.	B．Sky glow has a bad effect on their sleep.
C．Sky glow affects their viewing stars.	D．Sky glow wastes too much electricity.

4. What is the best title for the text?

A．Light pollution

B．Plastic pollution

C．Star pollution

D．Air pollution

7 . Cows produce much methane (甲烷) the world’s second worst greenhouse gas, as they break down the grass. They are a large source of the greenhouse gases that are driving climate change. Now scientists have shown the pollution from cows can be reduced by adding a little seaweed (海藻) to their food.

Recently, the researchers from the University of California studied 21 cows on a farm for about five months. They taught the cows to get their food from inside a special hood, which allowed the scientists to know the amount of the methane the cows were giving off. They added a small amount of seaweed to the cows’ food.

The consequences were surprisingly good. In some cases, the cows produced 82% less methane. The improvement depended on the kind of food the cows were given. Even the worst-polluting cows produced 33% less methane. Over the five months, the scientists didn’t see any signs that the cows’ stomachs were getting used to the seaweed and starting to produce more methane again. What’s more, the cows that were fed seaweed gained just as much weight as the other cows.

But there are still some big problems with the idea of feeding cows seaweed. For one thing, there’s not enough seaweed to feed all of the cows in the world. So farmers would have to figure out a way to grow lots of seaweed. A bigger problem is that for most of their lives, cows live in the fields, where they eat grass. That means there’s no chance to feed them seaweed every day.

Still, as the study shows, something as simple as feeding cows seaweed can help reduce some of the pollution causing the climate crisis.

1. Why did the researchers carry out the study?

A．To test the effects of the seaweed.

B．To discover healthier grass for cows.

C．To improve the cows’ living conditions.

D．To measure the amount of methane in the world.

2. What’s the third paragraph mainly about?

A．The background of the subject.	B．The results of the study.
C．The content of the experiment.	D．The process of the research.

3. What is the biggest challenge in the researchers’ opinion?

A．Seaweed is not as tasty as grass.

B．Seaweed is dying out in the world.

C．Cows fed with seaweed gained weight easily.

D．Cows can hardly have daily access to seaweed.

4. What is the author’s attitude towards the findings?

A．Positive.

B．Doubtful.

C．Unclear.

D．Negative.

8 . My sister Alice and I have been trying to get people to stop dropping cigarette butts (烟头) for seven years. One day, we were walking in our hometown and saw hundreds of cigarette butts on the ground. They made the town look so ugly that we decided to start a group to make people stop dropping butts. We called it “No Butts About It”.

At first, we drew pictures with “The Earth is not your ashtray (烟灰缸)” written on them. We put the pictures around our boomtown--in parks, by beaches, and along roads. We wanted to make people understand that dropping butts hurts the environment. Most smokers don’t think that dropping butts hurts the Earth. But it does, and all rubbish does!

Later, we wrote to companies and asked them for money to help us. We used the money to buy ashtrays to give to smokers. We wanted smokers to carry the ashtrays with them so they didn’t have to drop butts.

At the moment, we are trying to get cigarette companies to put an ashtray in each pack of cigarettes. Some companies want to do it. Many people have started to join our group since it began. Today there are 45 other “No Butts About It” groups in America

Now there are even groups in England, Australia, and India! Many newspapers have written about my sister and me over the last seven years. And we have won many prizes for what we have done. But we are not interested in prizes. We just want to make the Earth a better an cleaner place for animals, plants and people.

One day, it will be.
